LOCK.

Application filed July 15,

My invention relates to an improvement in locks and the novelty consists in the adaptation and arrangement of parts as will be more fully hereinafter pointed out.

There are many locks on the market and also many which have been patented which have various combinations of tumblers and are in certain ways adapted to prevent the picking of locks by those not having the proper key but all of such locks which are in any way efficient are ditficult and expensive to manufactureand also practically all can be picked by those skilled in this art.

My device is not only adapted to be manufactured easily and at a comparatively low cost but is so combined with an interlocking member which is controlled by a combination lock that one having the keys for the lock and knowing how to operate them will still be unable to unlock this lock when the interlocking member has been thrown into engagement and the combination set against the turning out of engagement of the in terlocking member. This combination of the ordinary bolt or look combined with the in terlocking member which is controlled against removal by a combination lock absolutely prevents the picking of the lock and throwing of the bolt by any other means than the proper adjustment of the combination lock member so as to permit the interlocking member to be disengaged.

My lock is particularly adapted to be used on a trunk or bag.

Referring to the drawings-Figure 1 is a front elevation of my lock as applied to a trunk or bag. Figure 2 is a detail of the lock asshown in Figure 1, sufiicient parts being broken away or shown in dotted outline so as to show the complete mechanism. Figure 3 is a side view of the lock shown in Figure 2 showing said parts in dotted outline. Figure 4 is a detail of the rotating tumbler or dial shown in Figures 1, 2, 3 and Figure 5 is a detail of the broken annulus shown in the lock in Figures 1, 2 and 3.

My device is particularly adapted for use in connection with trunks and bags as shown in Figures 1, 2, 3, 4i and 5 in which a plate member 58 is adapted to be secured at 59 to a trunk or bag body 60 having a cover member 61 on which is rigidly secured at 62 a hasp 63 hinged at 6& and a tongue member 65 adapted to engage in opening 66 in said plate member 58. A bolt member 67 is mounted on the back of said plate member 58 1924. Serial N0. 726,070.

under constant upward spring pressure of springs 68 which lie between said bolt member 67 and a base member 69 rigidly secured to the back of said plate member 58 and said bolt member 67 has a cut out portion 70 for the purpose of mounting said springs 68 therein. A button 71 is mounted on the front of said bolt 67 projecting through said plate 58 thereby permitting the movement of the bolt member 67 downward against the spring pressure of spring 68 and releasing the bolt 67 from engagement with tongue 65. The bolt 67 has tongue members 72 and 7 8 projecting downwardly at the lower end on either side of the base member 69 and a frame member 74 terminating at its base in a circular frame member 75 is mounted on the back of said plate 58 acting as a guide for said bolt 67 and a circular plate 7 6 of smaller diameter than 75 is rigidly secured to the back of the plate 58 inside of the circular frame 75. A broken annulus 77 having an annular cut out portion 78 on the top side is adapted to be mounted in the circular opening between 76 and 75 and a small annular member 79 is rigidly secured to the back of the plate 58 in the circular opening between 75 and 76 in absolute alignment with the base member 69 so that the tongue members 72 and 73 may pass down over both the base member 68 and the annular member 7 9. In order to effect openings 80 and 81 between the end of the annulus 77 and the fixed annular member 79 so that the tongue members 72 and 7 3 may project therein it is necessary that the annular member 77 be rotated to the position shown in Figure 2 which will be accomplished by the movement of a tumbler 82 having a pin member 83 projecting vertically from the back of said tumbler adapted to engage the annular groove 78 of the annular member 77 thereby rotating the same as the tumbler 82 is rotated. The tumbler 82 has cut out members 84 adapted to align with and receive the tongue members 72 and 73 of the bolt member 67 and the cover plate 82 is adapted to be mounted over the back of the annular member 77 and the circular frame 75 to be securedin position by means of a notched numbered dial 85 mounted on the front of the plate 58 and being so secured to the cover plate 82 by means of pin 86 tl'at the dial 85 and cover plate 82 will a together. The dial 85 is numbered as :rodici'zted at a, b, c and cl and by the turning'of'these numbers to :the point indiated at 87 in accordance with the prearranged scheme the annular member 77 may be turned tothe position desired so that the openings 80 and 81 are in alignment thereby permitting the bolt member 67 to be thrown down to disengage the tongue 65 permitting the hasp 63 and tongue 65 to eiiect the unlocking of the trunk or bag. The tongue 65 when re-engaged for locking by the bolt. 67 then permits'the turning of the dial 85 throwing the annular member 67 out otposition and closing the openings 80 and 81therebypreventing the unlocking or throwing down of the bolt 67 from the engagedrposition of the tongue 65.

I claim:

1. A lock comprising a plate, an arcuate frame mounted thereon and having parallel spaced end. portions, a bolt slidably mounted between said end portions and having spaced tongues adapted to enter the arcuate portion of the frame, spring, means located between thetongues for urging the bolt and to normally retain thetongues away from the areuate portion of the frame, a tumbler -.mounted upon the arcuate portion of the frame and havin notches ,for the rece tion friction-ally engages in said groove.

of the end portions ottlie tongues, means for rotating the tumbler and an interrupted annulus member received within the arcuate portion of the trame and interposed between the tumbler and the first mentioned plate.

A lock comprising a plate, an arcuate frame mounted thereon and having parallel spaced end portions a bolt slidably mounted between said end portions and having spaced tongues adapted to enter the arcuate portion of the frame, spring means located between the tongues torurging the bolt and normally retain the tongues away from the arcuate portion of the frame, a tumbler mounted upon the arenate portion of the frame and having notches for the reception of the end portions of the tongues, means for rotating the tumbler, an interrupted annulus member received within the arcuate portion of the frame and interposed between the tumbler and the first mentioned plate, said annulus member having a curved groove and the tumbler having an outstanding pin which In testimony whereot I a'lfix my signature.
